ToaZZ whom it may concern,.-V

i 13e known that I, `EDWARD TrAQAKAss, a citizen of the-UnitedStates, l cago, in the county of Cook and State of Illi- "nois, have invented certain 4new, and useful residing at` Chi- Improvements in Binding-Files, of `.which the followingzis a specificatitm.` w

i "lhisinvention relates to improvements'in binding in which the leaves orjinserts of any kindfasuch as pamphlets,mnsic, newspapers, or the `manner to like`1nay beremovably secured in a i "moval o. any of said removable sections withont` removing or displacing the associated parts. i l

The object oi' the` invention is to provide a Y strong and durablebinder .in ,which the curved `can be made in lengths suitable `1 est backs and reduced forshorter sizes by cut- Rprongs `for hold ing the leaves are integral with the hinges to insure rigidity and .the concen-` tricityof said `.said hinges.

said halves may be opened ont y ofthe several larly pointed out 1n the claims.

`The fnrtherpbject of the inventionis to improve and simplify the construction and. .in-

crease 'the economy and efficiency of the binder.

`1'10 these ends the invention consists in' the construction, combination, and arrangement parts of the binder, asiwill be hereinafter more fully described, and particu- In`4 the aecompanying` drawings the same reference characters indicate the same parts of the invention.

Figure 1 is a front open view of my improved binder; Fig. 2, a detail, ona larger scale-than' lf`g.` 1, oi' the lower hinge and prongs in closed position; Fig. 3, a detail in section on the dotted line 3 3 `of Fig 2, and Fig. 4 a detail inend viewof the back in open position of `the hin-ge and' prongs.

Thetwocovers 5 of my improved binder are connected by iiexible joints or hinges G to the `two parts or halves 7 of a back. The two halves 7 `are ,connected by hinges 8, whereby from each permit of the easyand quick re' hooks springing back.

actual practice,

sides 12.

-the spring-lever respective covers are made t'o open. 4The back hasthe tWo inside parallel metal bars 9, to

which the straps 10 of the hinges are securely fastened in any suitable manner, as by riveting, as shown in the drawings. These leaves are bent in thedirection of the covers at right 'angles to the bars 0, as may be curved, if a round instead of a square cornered back is desired. These bent leaves are' riveted, as shown at 11, to the sides 12 of the back and terminate thence in thepins or prongs 13 and 14, which are bent on a curve described from the pintle of the hinge' 8 as a center.

from opposite sides of the These will be parallel and separated a suitable distance, usually about an inch in and in order `to secure this separation the leaves of the hinge are set diagonally-of the back, as clearlyishown, and the hinge is at a corresponding Obliquity to the edges ofthe saidleaves.

In order to stiii'en and strengthen the sides i. ofthe back, I provide the metal plates 15 between the leaves of the hinges` and the These plates 15, however, are not essential features of the device.

The sides l2 and the bars 9 are held at right angles to each other or `at whateverposition has been determined by the plates 16 and 17, having the lugs 18, which latter are riveted to their respective holding parts. The bars 9 may be made up with their hinges in lengths great enough for the longest books and are quickly adapted to shorter ones by cutting off the ends of the bars before the plates 1li and 17 are placed, and the latter are then riveted at the required points. This is a great convenience and economy in the mannfacture of binding-files Where the manufacshown, or they` Each hinge will'. thus providetWo-v other in thesame general direction 4as their turer must be prepared to supply the demand I for books of various lengths.

Tile plates 16 4and 17 ailrd attachment for a fastener by means of which the back halves are locked together. This fastener comprises 20, riveted at its end to the inside of plate 1li and projecting beyond plate 16 and terminating with the outwardlybeveled hook :31, which engages the slot .2 in the plate 17. 'lhe lever is pressed in lo dis- IOO VIt isnot desired to limit the invention, however, to this particular locking device, as va-v rious other suitable means may be used.

'For taking a page or any detachable part from the binder the lile is opened like an or-I dinary book at the point where the desired leai` is located. When the back is next opened thepages on either side willbe carried away with the cover, but will be held together in their proper order by the pins or prongs 13 covers and 'back of the binder.

and 14, which pass through suitable .perforations in said leaves or -other suitable eyelets connected with the said leaves. Vhen so opened, a page can be readily taken from the binder, while its insertion is similarly effected with great facility. u

` I prefer to use four hooks for each bindertwo Vspringing from each side of the back of binder,.as shown; but this number may be varied, if desired.y y

It will be noted from the drawings that the metal bars 9.are of the same length as the This is important for the reason that it protectsthe locking device and stirfens and'strengthens the lower end of the back and covers when the file is stood on end on the shelf, where they are commonly kept. Vithont this stilening of metal the cardboard material of the binder would soften by use and wear and the weight of the le contents, causing the file to lose its shape.

Having thus f ully described my invention,

what I claim as new, and wish to secure by v l. A binder comprising a one-.piece flexible back, stilEening-bars on each side of the longitudinal middleof the back of the same length as said back, hinges having leaves rigidly secured, to said bars, said leaves terminating in impaling-hooks curved in the arc of I assess" i. eifel@ geniale; @fueran-siagetef of the hingepntle.

. 2,. Abinder'comprisinga'pair'ofjcovers, a one-piece iexible baclif integral with said covers, a pair of barsl longitudinally of the back secured to the inside one on' each side of the mid-line thereof, hinge connecting the bars and the back sections set diagonallyof said back, said hinges terminating in impaling-prongs curved on a circle centering at the pintle of the respective hinges, said prongs being at right angles to the longitudinal dimensions of the back.

3. A binder comprising a pair of covers con-- nected by a one-piece flexible back, a pair of stiening-barsminges between the stiffeningbars, said hinges having leaves which are fastened to the bars and terminate in curved impaling-prongs set to point inwardly from either side of the back, and a spring-lock secured to the inside of the divided back to hold the divided sections in closed position.

4. In a binder comprising covers connected bya one-piece flexible back, a pair of bars secured to the inside of the back longitudinally thereof, plates transversely of said bars at right angles thereto secured at the ends of the bars and having a spring-latch in one Vplate adapted to engage a catch in the other plate, 1

and hinges midway of the said parallel bars, said hinges having nally from bar idly secured, and thence around the inside of leaves which pass diago to bar to which they are rigthe back and terminate in impaling-prongs positioned at right angles. tothe back and curved on a circle described from the center of the hinges.

In witness whereof I have hereunto set my hand and seal, at Indianapolis, Indiana, this I 22d day of September, A. 1902.`
